# Thread: Everything comes from Pi

1. ## Everything comes from Pi

Here is the Children Video where this Pi Math Comed From

Here is a Grade 6 Children Book I wrote where everything comes from and goes into Pi...

Tedious, incomprehensible, delusions of significance ...

If you cannot say something clearly, you do not understand it (and just to be clear, you have not met the clarity requirement).

The type of nonsense we see all the time from a certain type of otherwise normal-ish person.

I won't be quite that harsh but I have to admit that I have no idea what you think you are saying.

Could you say, briefly, what "Everything comes from Pi" means?

I notice you include, in the title, the words "fractal" and "binary" but there is not mention, and certainly no definition of either in the body.

(I do notice a reference to "Gummy LSD". Perhaps it is the "LSD" that explains this!)

I notice the credits mention a Ween Shinola.

Maybe this is a case where we can't tell sh*t from Shinola!

Oh that's bad. (grumbles) I should ban you for that one!

I don't think Dan has sufficient privilege, though I would have thought he should have.

Hello, ashesmi!

A children's video?

I don't see how repeatedly bisecting a line segment
. . somehow leads to $\pi.$

Nor do I see how a sine curve with repeatedly doubling frequency
. . can lead to $\pi.$

Speaking as one whose mathematical notions are still in the oven baking I can plausibly ask questions that a sixth grader might ask.

You seem to be implying that because there is ONE, there is 1:2, (or reversing the video 2:1), because there is 1:2 there 1:4 (and 4:1) which means we have a representation of 1:8 and 8:1, and so on. By extension I suppose you are saying that all numbers can be thought of as equal divisions of unity (?). One can extend the representation to include dividing unity by thirds or sevenths or 47ths, etc.

But what about pi. Isn't the unsettling point the fact that no matter how many times you wrap the diameter of circle around its circumference you will never land exactly on the point from which you started (get back home!)? The central notion that you seem to imply, that ALL numbers (not just the rational numbers) can be generated by dividing a whole into equal parts is not true. But, perhaps, my notions are fifth grade, perhaps I am missing the point.

PS. Way above my pay grade but could one concoct a geometric surface in which there are no irrational numbers for two dimensional figures, that pi is even, that the hypotenuse of a right triangle is rational. This IS the philosophy section so why not speculate even if only to myself ... will get back to this in about 10 years.

The more I review the OP's video, the more annoyed I get.

It begins with a portrait of what could be the illegitimate son
$\quad$ of Chris Angel and Alice Cooper ... for a full minute.
The rather angry music doesn't prepare me for a rewarding
$\quad$and enlightening mathematical experience.

Repeatedly bisecting a line segment produces the sequence:
$\quad 1\;\; \frac{1}{2}\;\; \frac{1}{4}\;\; \frac{1}{8}\;\; \frac{1}{16}\;\; \cdots$

This is a list of rational numbers.
But $\pi$ is not only irrational, but transcendental.
I see no connection.$\;\;$What is your point?

Then you begin with the mystic Yin-Yang symbol which
$\quad$evolves into the graphs of $\:f(x) \:=\:\sin\left(2^nx\right)$
Again, I see no connection.

The mention of "Fractal Binary" doesn't clear up the mystery.

The last 30 seconds is a blank screen, with a plaintive song.

Do you think this video is a blessing for an 11-year-old?

Now showing for fans of crackpottery and B movies: Everything comes from Pi

Written and produced by promising newcomer ashesmi, the alleged enlightening video, having gained a forum view of 229, has so far earned the following glowing bad reviews:

Bentham had a great phrase "Nonsense on stilts."

But this goes beyond: it is boring nonsense on stilts.

14. ## Re: Everything comes from Pi

Apparently, this is "Liquid Science Development", not math, per se. It's too bad, the contemplation of $\pi$ leads to some truly fascinating stuff- the radius of a circle corresponds roughly to a notion of "distance" (see, for example "metric spaces"), something that continues to be true in arbitrary dimensions (we use "higher-dimensional circles" ($n$-spheres)).

It turns out the the "conversion" of linear motion to rotational movement involves $\pi$, one may therefore think of the number $\pi$ as "a half-turn". This turns out to be enormously profitable in many scenarios, such as analyzing fluctuating circuits, signal processing, force diagrams, and the like. $\pi$ is the first positive "zero" (root) of the sine function. The sine function (and its sister, the cosine) serve to turn lines (cosets of the $y$-axis in the additive complex plane) into circles, something expressed in Euler's beautiful formula:

$$e^{i\theta} = \cos\theta + i\sin\theta$$

This *is* the connection between viewing the plane as a set of "grids" (rectangular coordinates), and a set of concentric rings (polar coordinates).

Interestingly enough, this lies behind the fact that exponents of a given base are "easy to multiply" and logarithms are "easy to add" (the basis for why slide rules are so effective). It also explains why certain things are easier to "do" than "undo"-the line wraps around the circle "many times", so information is lost in the process (we know where we end up, but aren't "exactly" sure where we started).

It's unfortunate that neither the pdf nor the video explore these truly fascinating subjects. But hey, "fractals", right?

"Fractals"
